15 error codes

CodeMeaning
577-0577-0 is a control board internal fault that only surfaces in service diagnostic mode, not on the main display during normal use. The board's basically saying it logged something weird in its EEPROM at some point. It's not an active warning. It's more like a timestamp of a past event the processor decided to remember.

6-3The KitchenAid dishwasher error code 6-3 indicates that the control board has detected excessive suds or foam inside the tub. This condition prevents the wash pump from circulating water effectively and can cause the pressure sensor to provide inaccurate readings.
lowbeginner
8-4The 8-4 error code means the control board detected a heater circuit fault. The heating element didn't raise water temperature to the required level within the expected cycle time. It shows on KitchenAid models with a digital display and it's equivalent to the Clean light 7-blink code on indicator-only models.
moderateintermediate
9-1The 9-1 means the diverter disc didn't reach its expected position during the cycle. That disc routes wash water between the lower rack, upper rack, and third rack spray zones on KDTM models. When it doesn't advance on time, the board kills the cycle and throws the code. Same exact fault as 9 blinks on the Clean light on older models without a digital display.
moderateintermediate
CLEAN-4-BLINKFour blinks means the control board's thermistor circuit is open or shorted. That NTC sensor in the sump isn't sending back any temperature data, so the board can't run the heating cycle properly. Basically the machine lost its thermometer and it won't guess.
moderateintermediate
CLEAN-7-BLINKSeven blinks means the control board fired up the heater circuit but never got confirmation that water temperature hit the target. Either the element didn't draw current, or the high-limit thermostat cut the circuit early. The board logged it as a heater fault and threw the code.
moderateintermediate
CLEAN-8-BLINKEight blinks of the Clean light means the control board detected low wash performance. The dishwasher finished a cycle but the washing conditions, like water pressure, temperature, or spray arm coverage, fell below its minimum thresholds. This isn't typically a failed component. It's a performance fault pointing straight at maintenance issues.
lowbeginner
CLEAN-9-BLINKNine blinks of the Clean light on a KitchenAid dishwasher means the diverter valve or diverter disc motor has a fault. The diverter system controls which spray arm zone receives water during the wash cycle - routing water between the lower spray arm, upper spray arm, and (on KDTM models) the third rack spray bar. A failed diverter means water may only spray from one zone.
moderateintermediate
E1 F9E1 F9 means the control board timed out waiting for the water level to drop during the drain cycle. It allows roughly 2 minutes. If the float switch doesn't confirm the tub's empty in time, it shuts everything down to prevent flooding. It's almost always a physical blockage, not an electrical failure.

F8 E4F8 E4 on a KitchenAid dishwasher means the control board did not detect that the dishwasher filled with water within the expected time, or the anti-flood float switch under the unit has been triggered by water in the base pan. The dishwasher shuts down to prevent damage. This is the highest-volume fault code for KitchenAid dishwashers.
moderatebeginner
F9E4A KitchenAid F9E4 means water accumulated in the plastic drip tray under the main tub and lifted the safety float switch. The board sees that signal and forces the drain pump to run continuously to prevent a flood. The machine won't do anything else until that float drops back down.

HUBKitchenAid uses three totally different ways to display fault codes depending on the model year. Newer ones show alphanumeric codes like F8 E4 on a screen. Older models with no display make the Clean light blink in a two-part pattern. Some show just a number like 8-4. Same fault, three different ways to tell you about it.
moderateintermediate
KITCHENAID-DRAIN-ISSUEAt the end of a wash cycle the control board fires up the drain pump to push water through the hose and out to your sink drain or disposal. When something blocks that path, or the pump itself fails, the water just stays put. That's what you're dealing with.
moderateintermediate
NOT-CLEANINGWhen a KitchenAid dishwasher fails to clean, it indicates a failure in the water circulation system, a blockage in the filtration assembly, or an issue with water temperature and detergent delivery.
moderateintermediate
POPO on a KitchenAid dishwasher display is not an error code. It means the Delay Start feature is active and the dishwasher is waiting to begin its cycle at the programmed delay time. The dishwasher is counting down the delay period and will start automatically when the countdown reaches zero.
